INSULATE.

Specification of Letters Patent. Patented June 14, 1910.

Application filed April 24, 1999. Serial No. 492,014.

To all whim fitimay concern:

Be it known that l, WILLIAM Louis Rensen', oft the 'town of Yorkton, the

Province of Saskatchewan, Canada, have ingraph outside wiring, and the priine object of the invention is to provide an insulator which will avoid the present necessity of tying the line wire to the insulator.

Other objects of the invention are to provide a simple and inexpensive insulator which can be quickly placed in position. and secured to the wire, and which is so designed as to prevent the accumulation of water or snow between the insulator and the insulator post or sujgaort. It consists ,entially in a base adapted to screw to the Y later support, the base being supplied i a deep channel passing across the u exteriorly threaded end; a tube designe o he received within an enlargement; tori l at the bottom of the channel; and e f. afapted to screw unto the upper thres end of the base, the pa'rts be ing,r arrange constructed as hereinafter more partie 'ly described.

is formed from a c L f' ne base bored centrally and 3, threadcorresjgonding to the thread on the support so the hase may screwed thereon. The upper end of the base diminishes in cross sectional area forming a shoulder at 5, and then extends upwardly where it is exteriorly threaded at 6.

7 is a deep channel passing centrally across the .upper end of the base, and the channel is enlarged at the bottom at 8 to receive the split tube 9 which passes completely thereacross. The enlarged portion of the channel is circular in cross section and instead of passing straight across is arched as at 8 so that the tube 9 is arched also when in posi-l tion.

l() is a rim extending downwardly from the base and it is to be noticed that the inner wall 10 of the rini tapers outwardly when passing upwardly and is continuous with a curved wall 11 which projects in a downwardly pointed rib at12 and then passes completely across the base at 13. My obliectt'or so constructing the bottom of the 4base will be shortly explained. The c'ap 4 is simply bored and threaded at 4 so as'to screw to the thread 6 and the central bore flares outwardly at the bottom at 14 so asto allow the cap to screw down tightly against the shoulder 5 of the base.

l5 are circular notches cut in the lower edge of the capand directly opposite each other, and they a're adapted to receive the tube when the cap is screwed into position.

16 represents one of the line wires.

ln order to better understand my insulator l will .now describe the manner in which the wire is placed in position The base is Erst screwed to the support and the channel Z is brought so that it will be in ali-nement with the channel in the base on the adjoining post. The wire held in such other channel is passed within the channel 7 of the insulator in question and a tube such as that 9 is placed onthe wire, the wire through the longitudinal opening in the tube. The wire is passed to thev lowest part of the channel, that is, into the enlargement, and the tube is then Iforced into the enlargement with the side having the longitudinal opening therein facing downwardly. Theewire is then stretched, allowing the proper slack between the adjoining posts, and the cap is applied to the base and screwed tightly to the shoulder. The notches 15 in the final position appear directly over the tube, which tends to a certain extent to hold the cap in position. The downward pressure ofthe cap on the tube when 1t 1s in" upwardly nel`- 7. Th

being screwed onto the base tends to close the open edges of the tube to ether, which makes it tit more tightly on the Wire, as is l best shown in F ig. l. The tube has been shown turned upwardly and with the opening continuous with the channel T in Fig. 2. Vhen the cap is screwed down with thel wille and tube in position the operation is complete. The arch inthe tube together with the pressure of the cap on the tube prerents thewire from slackening.

The enlargement 8 instead of beiiig'aijched `could pass straight across the base and in this the tube would be inserted within the enlargement with the longitudinal open`- and continuous with the chane wire. would then he inserted. ugithim the channel and in passing `downwardly would ente:` the tube which would afterurardbe turned over downwardly. By applying the cap and screwing to position the tube would be closed as in the previous case. However it is considered that the arched efect is preferable as it eiectually prevents longitudinai displanement of the Wire. It will of course be understood that the tube is formed from a very Hexible metal and that the insulator will be completely of glass.

My object in forming the bottom of the base as described is to avoid the accumulation of snow and rain between the base and the support as the presence of such is harmful, and with my insulator it is contended that the rain o r snow will not tend to lodge f with the openingbottom and arched, a

between the insulator and the support but will be driven by the sweeping effect ol the Wind downwardly from the insulator on account of the construction of the Walls l() and ll.

What I claim as my invention is:

l. An insulator comprising, a base having a threaded upper end with a crosschannel therein, said channel being enlarged at the bottom throughout the length thereof, a longitndinally split tube adapted to pass snugly Within` the enlarged portion of the channel and extend beyond the end thereof, and a cap constructed to screu1 to the threaded end of the base and bear on the extending end ofthe tube, as and for the purpose specified.

2. An insulatorcomprising-,a base havin a contractedupper end with across ehann ,.therein, said channel being enlarged at the tube designed to pass endwise snugly Within the enlarged portion of the channel and belongitudinally split i yond the ends thereof, the split in the tube being continuous with the upper end of the channel and a cap constructed to screw to the threaded end ot the base and engage with the extending end of the tube and close the split when the tube isl turned, as and for the purpose specified. Signed at Yorkton, in the Province of Saskatchewan, this 24th day of October 1908.
